Crestron ST-1550 & ST-1550C
Touchpanel as Part of Cresnet System
Operations Guide - DOC. 5803
This section of the Operations Guide only applies to those using the touchpanel in a
Cresnet System. It provides descriptions regarding programming via SIMPL
Windows and details on how to connect the panel to load a program.
Programming with SIMPL™ Windows® ®
NOTE: Graphical touchscreen design is accomplished using VisionTools Pro (VT
Pro). VT Pro is a Windows compatible software package for creating Crestron
touchpanel screen designs. Refer to "Software" on page 2 for additional details
regarding VT Pro.
SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programming language that is completely integrated and compatible with all
Crestron system hardware. The objects that are used in SIMPL are called symbols.
SIMPL Windows offers drag and drop functionality in a familiar Windows®
environment.
SIMPL Windows is Crestron Electronics' software for programming Crestron control
systems. It provides a well-designed graphical environment with a number of
workspaces (i.e., windows) in which a programmer can select, configure, program,
test, and monitor a Crestron control system.
The next two subsections describe a sample SIMPL Windows program that utilizes a
touchpanel. The first subsection details how the sample program works with a textual
description and block diagram. The second subsection provides a broad description
of how to actually create the SIMPL Windows program.
NOTE: The following description assumes that the reader has knowledge of SIMPL
Windows. If not, please refer to the extensive help information provided with the
software.
NOTE: There is no need to recreate the sample SIMPL Windows program. A
similar copy of this program is available from Crestron's ControlCD (version 5.1 and
later) or the Software Downloads page (Examples Library) of the Crestron website
(www.crestron.com). Search for the ST-1550C.SMW project in the SIMPL
Windows Example Base.
How the Program Works
A basic STS Touchpanel SIMPL program is shown on the next page in block
diagram form. For this example, the ST-1550C is the user interface in a relay-
controlled lighting system with four preset scenes and an OFF scene. To activate a
scene, the corresponding relay on the built-in low voltage relay card in the CNMSX-
PRO must be latched. To turn the scene off, use the clear function of the
INTERLOCK symbol to open all relays.
